TROUBLE DIAGNOSISPFP:00004
Trouble Diagnosis IntroductionEHS0016M
CAUTION:

Do not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness con-
nectors.

Do not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace
it with a new one.

Keep ground connections clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

Trouble Diagnosis: “AIR BAG” Warning Lamp Does Not Turn OffEHS0016V
DIAGNOSTIC PROCEDURE 6
1. CHECK CONDITION OF AIR BAG MODULE
Inspect for any deployed air bag modules or seat belt pre-tensioners.
Are any air bag modules or seat belt pre-tensioners deployed?
Yes >> Refer to SRS-60, "COLLISION DIAGNOSIS" .
No >> GO TO 2.
2. CHECK THE AIR BAG FUSE
Check 10A fuse [No. 13, located in the fuse block (J/B)].
Refer to PG-4, "
POWER SUPPLY ROUTING CIRCUIT" .
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. CHECK AIR BAG FUSE AGAIN
Replace 10A fuse [No. 13, located in the fuse block (J/B)] and turn ignition switch ON.
Does the fuse blow again?
Yes >> Repair harness.
No >> Inspection End.
4. CHECK AIR BAG DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and touch “START”.
Is
“AIR BAG” displayed on CONSULT-II?
Yes >> GO TO 5.
No >> Visually inspect the air bag diagnosis sensor unit har- ness connections. If the connections are OK, replace
the air bag diagnosis sensor unit. Refer to SRS-58,
"Removal and Installation" .
5. CHECK HARNESS CONNECTION
Check for loose connections between the combination meter and the air bag diagnosis sensor unit.
OK or NG
OK >> Replace air bag diagnosis sensor unit. Refer to SRS-58, "Removal and Installation" .
NG >> Properly connect the combination meter and air bag diagnosis sensor unit harness connectors. If “AIR BAG” warning lamp still does not turn off, replace the wiring harness.
